hey guys this my first post and i juz wanna ask if it is advisable to upgrade to a new firmware..my firmware is 2.50 and it works great on me!and may i ask what is latest firmware for the 3650 in the philippines?!tnx a lot!
Basically, if the phone works fine, it's not worth upgrading. Most of the newer firmwares fix particular problems with certain network operators - if you are not suffering from those problems, then there is no benefit in upgrading (and you are likely to lose all your data, and be without your phone for a period of time).
Finally, not all networks have approved the newer firmware for use, so simply because someone else has a later firmware in another country doesn't mean it is available for you or your network.
