Just got my self a 3GS. Today, I fully charged my iphone. Went to work, and listened to the ipod for 3h 40min. And now, my battery is down to 27%. Seriously, what shall I do? Push is turned off, Wi-fi also. Shall I return the phone? I mean, come on, the spec says at least 24h of music listening. I'm really getting pi**ed off. Advice anybody? And if you think I shall return it, how will I have to deal with the fact that I've jailbroken my phone? Is there away to "un-jailbreak" it so the people att Apple won't blame me for that?
