I was wondering if you can use texting from applications on a Jailbroken IPhone, NOT under the ATT network and does NOT have internet access. Poorly worded, let me try to elaborate. I have a 1G IPhone that is unlocked and I am using the T-Mobile network. Can I use applications like TextFree, SKYSMS, or AIM to send text messages without being charged? I am under the assumption that these apps use the internet, but Safari does not work for me unless I am in a WiFi hotspot. Can I use Texting even if im not in a WiFi?
