My sister has an Iphone 3G that i passed down to her when i got my IP4. Well its extremely slow and very very glitchy. Last night i did a hard reset on it and took about 25 minutes to reboot. It takes about 30 seconds for the text messages to pop up after you press the message icon. Any tips for speeding it up a little or at least get it not so glitchy. Thanks in advance.
