It’s been a while since I’ve had anything useful to add to my iPhone tips series. I just ran into a problem today that I thought worthy of mention.

Having got my iPhone working in the UK with T-Mobile’s data service, I returned today to the USA and put my T-Mobile US sim card back in. I had some problems getting the EDGE data service working again. Since last I used the T-Mobile US service the APN settings seemed to have changed. The following settings are now working for me:-

  • APN: epc.tmobile.com
  • User: (blank)
  • Password: (blank)

A second problem I had was that the “Cellular Data Network” tab had disappeared from my Network Settings page. The fix for that is to check in Cydia and UNINSTALL any APN fixes or T-Mobile/T-Zone bundles you may have installed. Then restart your iPhone and the tab should be back on the Network page. That worked for me just now!

I hope that proves helpful for anyone facing similar problems.
