Will OTA delete my contacts?

I forgot if it deletes contacts and such?? I have a mac and dont have it backed up.. Thanks. Enjoy the update!

My contacts were all missing after the upgrade through DM. I just did a restore through DM. Not sure how it will work with a mac or with the OTA upgrade. I also have a macbook, but did the upgrade on my pc.

I will have to wait for my dad's laptop he has DM on his.. I thought the point of OTA was that it doesnt delete your information????

It shouldn't delete it

Here we go!!!

hey guys . what will happen if i dont back up my storm before installing the new update? will i loss all my numbers, pics, tones, etc. please help fast
