Bit off topic but have you thought about flashing a custom ROM?
I have a Desire HD and flashed a custom ROM after HTC said that they were not going to release ICS anymore. I first flashed a ICS ROM which was good but performance took a bit of a hit. I recently (about a month ago) flashed JellyBean 4.1.2 and it works perfectly. Performance is same or better than it was with the original stock ROM and everything (as far as I know or have used) works just fine.
It gave my Desire a new lease on life. Was going to replace it but can now hold on until the Galaxy S4 comes out next year.
