I have a Nokia 6600 and I want to switch it to the 4.0.x firmware to fix a few bugs in the J2ME environment. I went over to my local T-mobile store and they said that they couldn't do it and I should contact Nokia. Is there any chance that I could download the new software from somewhere and install it myself? I have Bluetooth and I'm not averse to installing things on my phone. If there is a download link somewhere, please point me to it.
