I was in the US Cell store in my area last week and I asked about 2.2 being released basically just wanting to know if and when.
The rep told me they were looking at sometime in October. He did not give me a specific date.
Not sure if this was just BS as this wouldn't be the first time a sales rep has lied to me but I am feeling hopeful.
Casper, this might answer your questions.
I am excited about native exchange calendar support and the overall speed enhancements as well as the new version of flash that is included in the release. I am excited about flash just because it will expand that amount of streaming video you can recieve on the device.
