I got a 6110 navigator from mtn this wknd and have had no problems!! The gps is AWESOME and the phone has none of the normal nokia lag. Battery life is better than the n95 I used a little while ago. Even after using the gps for 2 or so hours, being on mxit for an hour or two, using the hsdpa, making calls, taking videos and photo's and sending a bunch of messages purposefully trying to run down the battery it still lasted just over a day!! Which means normal use should get you by for 2-3days. The panorama is also pretty cool. you press the button once then just the phone and it takes the rest for itself!
The two speakers are VERY LOUD and you can hear the gps fine while you're driving even with the radio on. I just want to get a holder cause i'm busy holding it while i drive.
Music through the speakers is also very loud and clear
All in all i've tried to find any fault whatsoever with it so if there is any problem I should change it, but still in vain. It's a great phone and i'm not gonna let it go!! Mtn apparently has stock in its warehouse, so if you want one i'd say tell them to fetch it!
6110 Navigator is AWESOME!!!!!!!!!!!!!!!!!!
