Well.....I downloaded the update from the link in my earlier post. As soon as this was installed, I was prompted to install an update which was also successful. I then tried the software update which said that I was up-to-date (with V1.5). I found out through the T-mobile forum that they had taken the 2.1 OTA update down temporarily, however, at lunchtime today, the update was up again and I now have 2.1 installed problem free.
