Problem: So your paying AT&T plenty of money to use their slow, spotty, 3g network. AT&T and Apple have gotten together to tell you what apps can and can NOT use 3g data. One of your apps that you need to use anywhere is only allowed to access the internet via WiFi.
Solution: Jailbreak your iPhone and install VoipOver3g via Cydia. VoipOver3g will trick your apps into thinking they are using WiFi, when really only 3g is available. To tell VoipOver3g which apps to allow you need to add the bundle identifier to the /Library/MobileSubstrate/DynamicLibraries/VoIPover3G.plist on your iPhone.
How to find an applications bundle identifier:
- ssh into your iPhone
- cd /User/Applications
- find . |grep appname
- cd into the long folder name
- cd in appname.app
- nano Info.plist
- find <key>CFBundleIdentifier</key>
- key should be just below it: <string>com.vnetcorp.sipphone</string>
- nano /Library/MobileSubstrate/DynamicLibraries/VoIPover3G.plist and add to list
Simply add that string to your /Library/MobileSubstrate/DynamicLibraries/VoIPover3G.plist, reboot the phone, and that application should now be able to access the internet over 3g!
Problem: You want to send someone a large file but your email provider doesn’t allow attachments over a certain size.
Solution (in no particular order):
- http://senduit.com/
- http://rapidshare.com
- http://www.mediafire.com/
- http://www.filemail.com/
These service providers allow you to upload a file. You get a web link to that file, which you can email or IM to the person you wish to download the file. That person simply clicks on the link, and begins the file download.
NOTE: Most of these sharing sites do not authenticate the downloader. This means that if someone guesses the URL of your file, they too can download it. While this is not likely, it should be something you are aware of. You can add another layer of security by zipping the file with a password, or encrypting the file before uploading.
I have a few users who get errors when trying to IMAP or POP their mail from google hosted (gmail users can also run into this problem). If your settings are correct and everything was working and has just stopped, you may need to un-lock your account via Captcha.
Exactly how accounts get locked is a bit of a mystery. Although, I have a feeling it has to do with checking an email account too frequently, and maybe from multiple devices coming from a single IP address.
For the solution please follow the steps below to resolve the problem:
- Disable all mail clients you’re using to read Gmail messages. (If you use one at work and one at home, please disable both.)
- From the computer on which your logins are failing, visit http://www.google.com/accounts/DisplayUnlockCaptcha
- Enter your Gmail username and password, and the letters in the distorted picture.
- Once you have successfully logged in, restart your mail client and try to download your mail.
If you’re using a Google Apps email address, please instead follow the steps below:
- Disable all mail clients you’re using to read mail. (If you use one at work and one at home, please disable both.)
- From the computer on which your logins are failing, visit https://www.google.com/a/[your domain].com/UnlockCaptcha. Be sure to fill in your domain name in the URL.
- Enter your email username and password, and the letters in the distorted picture.
- Once you have successfully logged in, restart your mail client and try to download your mail.

Occasionally I run into the error message that a volume can’t be ejected because it is in use. Even though I don’t actively have anything being used on the share. Today I got fed up with the error and decided to find a solution.
- Application: lsof – list open files
- Usage: lsof | grep sharename
- Example lsof | grep files
This will return a list of open files on that share. You can then close the application that is holding the file open by either using the “Activity Monitor” or issuing a kill -9 PID.

I am constantly configuring firewalls and wireless access points for clients. It has always been a pain to have to go offline for a while, while I switch the computer to use a different IP address while I’m configuring the device. Today I was put in the same situation, except this time I’m using a Mac, and have a solution!
Its very simple, this is how its done:
- Go to System Preferences, Network
- Click the + symbol at the bottom of the device list to create a new interface
- On the interface selection, choose ethernet
- In the Service Name section, enter whatever you want to call the second interface, in my case Ethernet 2
Thats it! Your done. You can now configure the new interface to use whatever IP address you want and configure your device without leaving your native network. Of course, this can also be done using your wireless interface as well.

NO. Email is similar to sending a postcard. Anyone along its route can read it with ease. While it’s not likely that anyone is reading your email, you should never send anything such as your social security number, credit card numbers, or passwords, etc.
Most internet providers (aka. AT&T, COX, Time Warner, etc.) give you email accounts with your monthly internet access. Most people use these included email accounts, but my suggestion is to NEVER use them. Here are the reasons why you shouldn’t:
- Not very feature rich.
- More limited storage space.
- Address can be harder to remember (eg. something@san.rr.com)
- Tie you to their internet service. (BIGGEST REASON)
This means if you move out of their service area, or just want to switch to a different provider (because of pricing or lack of service), you are forced to change your email address. While not directly, this is similar to the drug dealer business model. Give them free email accounts, and they will keep paying their monthly fee for internet access.
You would be better off using one of the many free email accounts offered by various companies, such as Gmail, Hotmail, or Yahoo mail. This way your email is not dependent on your internet provider.
An even better solution is to sign up for Google hosted services. For $9/year, Google will give you email at the domain name of your choice. Basically you are only paying to register the domain name, and Google will host your email for FREE! This includes all of the legendary features of their standard Gmail.

Your domain name is the MOST important thing when it comes to hosting your website and email. If and when you buy a domain name, it is best to make sure that YOU are actually buying the domain name, NOT your web hosting company. This means that YOUR information is put into the Registrant, Administrative, Technical, and Billing contact information for the domain name.
This is very important because if your hosting company ever goes out of business, or you get into a dispute with them, you will not loose your domain name or access to it. Verification of ownership or to make changes to your domain is often done with the contact information you have listed, either via email, fax, or snail mail. If ANY of these methods are insecure, you risk someone being able to steal your domain name.
In the end, your domain name is the lifeblood of your online presence.
