A quick question about updating my Verizon iPhone to 4.2.10. Can I do the update on another computer other then the one that I normally sync it with and not lose all my data? I have updated my software 3 times and every time I have gotten an error and had to but in DFU mode and do a restore. After the restore the newest software was uploaded. Just kind of a hassle to go through a full restore every time I want to update. Thanks in advance.
