T-Zones $5.99 data plan working on iPhone

This guide is for T-Mobile users who have a jailbroken iPhone and want to get nearly full data services at 1/4 the cost of the normal Total Internet data plan (normally est $19.99). This does not require the T-zones hack from Cydia (the tzones hack actually made my iphone’s data not work w/tzones).

Requirements:
-Jailbroken or Simfree iPhone (obviously to use tmobile)
-Tmobile’s T-Zones internet data package ($5.99/mo)

The forums over at http://modmyi.com are the basis for this recipe. So this is what you could call a shared recipe. :)

After having a Jailbroken phone, go into Settings > General.

Then go to Network and then Cellular Data Network.

–Change the APN to: epc.tmobile.com
(if this does not work, you may need: wap.voicestream.com this is the older APN for tzones and works for certain areas only)

–Also be sure that “Data Roaming” is enabled from the Network screen.

NOTES:
-if you do have the total internet package, you can either use internet3.voicestream.com or internet2.voicestream.com in the APN setting; use wap.voicestream.com as a last resort since its been reported the connection speeds are slower even for the total internet package payers.
