I'm jailbroke on a iPhone 3G. My wife is too. I want to see if I can cancel the $30/month fee for unlimited texting - or find a better option, other than lowering the plan to $10/monthly for 100 texts, etc... Is there a way (JB or not) to send/receive texts on iPhone for free? I see BiteSMS but it requires credits? Ugh...other options?
