Hi Im new to this site and to the iphone, heres my issue...
I bought the iphone 2G 8GB from my boss she upgraded to the 3G sold me her 2G for $35. I figured I could just use it as an ipod touch (wifi, ipod, and games), well eveything but the wifi works, I have her old sim card it has a phone number but I cant get any wifi signal like on my laptop or my buddies touch.
I seen this thing called jailbreaking to fix this issue but not sure how to go about finding a reliable source to do it. Can anyone explain what it exactly is to me and if it does fix the wifi. or if there is an easier way to fix the problem Im having.
Im not slow but could you dumb it down for me until I pick up on the terminology for the iphone. Im sure you get this alot so sorry for the repeat posts and thank you in advance
