Out of all the phones I've had with Sprint over the years, this is only the 5th one that even had any capability to use a data plan.
First came the BLADE...slow slow slow POS phone but didn't think anything of it at the time as I had nothing to compare it to. Then came the Instinct....the supposed iPhone killer!! I was not impressed. Then I got the Palm Pre, which was a piece of junk as far as the hardware went, but was pleased with the OS. After my wife destroyed her Pre, she wanted to get the Evo, and with me being a spoiled brat, had to have one too. This was the best phone so far, although the speeds were horrendous. 3G was a joke. 4G was non-existant in most places, but completely killed the battery whenever it was being used. I used it a lot on Wi-fi and sold myself on the fact, that is the only time I would be able to enjoy using the phone, if thre was a wi-fi hotspot to connect to. So, I guess I can say that Sprint does have a pretty slow network overall, but now that I got the iPhone, it is without a doubt the fastest phone that I've owned yet. I can get full 3G speed while sitting at work, which I was never able to do with any other phone. YouTube and browsing is fluid, and I rarely have to wait for anything. I am fully pleased with Sprint now. Anything faster is just a bonus.
