Hi guys, I'm considering an iPhone 3G for my first cell phone but had a quick question about it and the 3G network. If i Lock my iPhone will it still be connected to the 3G network? or is it connected to the AT&T service only or is that the same? The reason I'm asking is because unlimited Texting is a bit steep for me so i was considering using TextFree seeing as it works so well for my iPod. With my iPod i use the Cydia utility "KeepAwake" that keeps the ipod's WiFi on while locked, but there is no such app to keep the 3G on so im wondering if its always on (so i can recieve txt's from my friends without keeping my iPhone on.) Thanks. Best Regaurds, -Fistof40k.
