Syncing iPhone 4 with different device.

[chriscool9]

Hello there all,
Basically I'm wanting to associate my iPhone with a different computer now. It was connected to my laptop but that has sine become unreliable and as such, would like it paired with my desktop. I've done some research but cant get a deiffinitive answer. If I 'Erase and Sync' will I loose everything? From what I understand it erases pictures (which ive backed up) and music. Am I correct in saying nothing else will be lost, ie Messages, Whatsapp, Contacts etc

Thanks
Chris

Erase and sync will erase your applications, application data, songs, movies photo album photos(not the camera roll). messages, phonebook, alarm clock, etc. will not be erased.
