Basically I want an iPhone 4, but am mostly around WiFi, I'd be ok with some data, but I really don't need it. I'm looking to buy the phone upfront, and maybe $20-$40 for service afterwards, but I'm open to compromise to keep it cheaper. As of now, I'm using an iPod touch with textfree but I need more stability. I would like unlimited texting (sms not needed) and maybe 500-1000 minutes a month... any suggestions? Also, I have no idea how to do a carrier unlock (or when its needed, even) but I do know how to jailbreak. ANY advice would be appreciated!
