Iphone/Itunes not syncing

[ghostfaced]

So today i brought my old phone in because my wifi wasnt connecting. they gave me a new one so now i have to resync all my contacts ringtones ect up. well when i connect my iphone to my computer (PC) it gives me this error.

itunes was unable to load provide data from sync services. please try to reconnect later.

the phone wasnt really recognized and all it did was charge and eject

i then connected it to my laptop (Mac) and it started to work so i thought it would register onto my PC and it did i could go through info and all that stuff but when i tried to sync up my old info it gave me a error of

itunes could not sync information to the iphone cdub503 because a sync session could not be started

im pretty much about to focus the shit outta my phone. the only thing i havent tried is to reinstall itunes. i was wondering if anyone else has had these problems or know how to fix this..... thanks

sorry to hijack, but I'm also having trouble with my brother's ipod. Plugging it in gives me a message that I have to format the drive in order to use it... I guess something got corrupted? I tried SharePod, but it doesnt get detected. Songs still play, but I just cant access it through the computer.
