Re: i phone I found
The problem with I phones/ I pod touches are they aren't made to be opened up. They are considered a disposable item once the battery goes (coming from the owner of one). Also the problem like most cell phones is once they are immersed in water or get wet, the charging circuitry for the battery get's fried and the cost to replace/repair is more than the thing is worth.
I'd say if you don't have an Ipod charger, take to someone who does. If it wont charge, then its garbage. IT may work without a battery while hooked up to a charger. In that case the original user might be able to recover data from their phone to I-tunes. Note, you if you do hook it up to a computer to charge make sure you don't tell your computer to sync to it.
