Moto Modding

Recently I again spent some time playing around with my Razr, which I had got almost 2 months back. Previously, I was only able to transfer pics from my laptop to the phone via bluetooth. But, now i can do more:
- I finally got a mp3 tune which I could send over the bluetooth and Razr recognized it. I think all my previous files were too big. It could handle upto 300 kb, but could not handle a 700 kb hindi mp3. And now, I have cool ringtones.
- I also bought a ringtone over the wap for a few bucks. Just to test, and I am not doing that again. Pretty neat tune though.
- Could get the Motorola Mobile Phone Tools sw via http://vxxxstuff.com/himself/vxxxprograms Neat thing. I can even dial via the sw from the phone over bluetooth. Could sync calendar, phonebook and multimedia. Finally, I could recover and put into my razr all my old numbers. (Which I had scanned and ocr-ed and kept ready for this express purpose)

And now I am onto modding. Started with my simple quest for a better search tool in the phonebook, now that i have zillions of contacts. It does not take in multi-letter searches and one has to scroll down after reaching the starting letter. And curse people starting with a or s. Anyways, so found these cool sites, where by you can flash the firmwire and get updated phonebook with this option. Aparently there are a lot of these from fixing various bugs, to unlocking phones, to enhancements etc. Need a usb cable though. There is a Motorola software called PST phone programmer which you can use to install all the new firmwares.
Here are a few links which might help one get started. Will do this after I move over to California, get my sim card changed to a local number, and get the amazon 150$ rebate :-)
