I have been looking for this and have missed it for the last week but the Windows Mobile 6 upgrade for my Cingular 8525 is available. You can find it on HTC's support page for the 8525. It took forever to download and I got some huge help from a friend but 4 hours later it is downloaded. My friend went out and got a tool called Fresh Downloads that would get 8 streams of download at one time and keep it in one file. That sped up the download and would let us resume where we left off when the server for HTC crapped out. Finally it is downloaded and it installed successfully in about 15 minutes. This should keep me interested in this phone for another 6 months.
