Personally, I have left my Pre2 completely stock with the exception of few PreWare apps. No overclocking and no patches. Although I'm contemplating the installation mode switcher, which would work best with a patch to autmoatically start it up. I want to use it to enable data on demand mode and save battery.
I got a cheap $2 screen protector from ebay. I much prefer the boxwave protector I had on my pre- & pre+. Because that didn't require water to apply. But other than that, my cheapo one is fine. Actually it's thick enough that it minimizes the lip around the glass.
I have also just ordered a Palm Pre 2. My previous PDA was a Handspring Treo 90. I have a number of applications and data stored on my PC from the Treo 90. Is is possible to transfer the Apps and Data to the Pre 2, so that the PalmOS emulator can emulate these apps? The Treo 90 OS was Palm OS 4.1 - is this even supported in the PalmOS emulator on the Pre2?
