Well I still haven't gotten a MIDP phone, or done any talkLock hacking. Now that my wedding and honeymoon are in the books, I'm going to take the next leap and buy a house.
I bought a Motorola Q on eBay, but it was the Windows Mobile one (doh!) not the MIDP one. It also didn't work well. The vendor is shipping me a replacement.
I spent a few minutes installing a MIDlet player on the old one, but it was faulty. I had heard that you can run MIDlets on Windows Mobile phones, but maybe not mine.
At the moment I'm hacking around and looking for my next project. I haven't really written any code other than shell scripts or Makefiles for quite a while.
