Nokia
Firmware updates. 3586i
and this w/ LITH ION battery.also the fact that almost everything has to be done w/ a $50.00 data cable also sucks. but the thing is hella loud and good sound so if i have to charge it nightly its not thet big a deal.also a good plus is that unlike most of the other carriers adapters can be used w/ other models... 🤣
