I've noticed over the last few months that my first gen iphone has started to become unresponsive and take a long time to load basic things like sms. I also sometimes cannot answer calls, slide to answer doesnt work or it does but freezes at the end of the bar and i cant get out of it unless the person on the other end cancels the call. I've tried a restore as well and its not been jailbreaked, although it used to be but i never really used cydia anyway.
Thanks
