only if the malfreemap team able to include all those "nice improvement" into the nokia maps 
imagine the stability of the nokia maps bind with the details on the malfreemap 

everything will be intact if u upgrade firmware... unless it failed/your phone bricked. but it's very rare provided you know how to do it carefully.

nt yet 

On the new firmware, earlier I reported that the "hang kei" issue while browsing the maps solved.....ehhh actually it's hang too in latest version..

Apparently I thing the "hang Kei" started when the phone started to get satelite fixed. So the only solution now is to avoid satelite fixed if need to browse map..i.e temporary disable acquiring satelite feature 1st

Hmnnn for me no wor...This version is the most stable version running GMXT...except once got the satelite fixed, the hang kei problem started...I will try later to disable the satelite acquisition onbce outside & check whether hang...

Yours...probably u install too many programmes already compare when u are on V31

Ok tested by keeps on dragging & zooming in & out.....Wth GPS on, it freeze minutes after getting the 1st fixed....Much stable than previous version...Later, me also tested by diabling the GPS function in GMXT...yeah it freeze too after few minu8tes of dragging & zooming in/out....Nothing to do wth satelite acquisition
