since i got my first BB, i always did a wipe and fresh install. Yesterday meanwhile, i did an update for 9900 because really i didnt feel like re installing all the applications and loosing some game scores * hehe * , and i did notice it backup everything and did restore through DM.
I noticed that at first boot after installation and before restore there was nothing on my bb, hence the restore. my question is, did DM some how partially wipe it ?
what are the pros n cons of Wipe vs Update using DM.
and if i did an update through DM, will these improvements, such as longer battery life, be in effect or is it necessary to wipe it ? Thanks all
