As the title reads, I am looking for some help/advice. My iPhone 3G has been very good to me and I am sad to say that the Ringer On/Off button finally broke off and now is unable to move. I got my 3G close to launch day and I am obviously out of warranty. I am eligible for an upgrade of either 3Gs or iP4 but I am not in able to do this because I do not have any money for the next month or two. (I am a student who is graduating) What are my options, I know I can dissect it and replace it however I don't feel like I am capable of doing this successfully. Also my friend has a iPhone 3GS within warranty, do you think we could go to the store and possibly have them replace my 3G using his warranty by saying something like he bought a 3GS and sold it for a 3G and now it's broken? or should we even mention the that mine is a 3G? I'm just kind of freaking out. Sorry for going on and on. Help!
