Sony Ericsson W580 / S500

ive been seeing this as a common topic & i should set something straight as i see it.. i work w/ warranty exchng dept & as i know it any tampering with the software installed w/ phn can be veiwed as voiding the warranty or a reason to consider an phn out of warranty per what manufacturer calls "unauthorized modification" so if u try to exchange unit w/ excahnge program with whatever carrier ur phn is pre programmed under it will come back to bite u w/ an oow fee.. 😈
