I am using a freshly jailbroken and unlocked iPhone 2G on 2.2 with my T-Mobile account. However, I have been having a lot of trouble with text messages, namely people not receiving half of the ones I send. I seem to be receiving all, but my friends can't say the same. If I go to Settings > General > Network > Cellular Data Network, these are my settings: APN = epc.tmobile.com Username = <blank> Password = <blank> Has anybody else experienced these problems? And if you aren't, are your settings the same as mine? Thank you. P.S. I also have a T-Mobile G1, so my data plan is the unlimited all G1 plan, in case that makes a difference.
