I don't buy that. If Sprint was doing some kind of upgrade that would make that dramatic of a speed increase you KNOW that the reps would be aware of it. Not to mention every tech site out there would already have the information.
that isn't something Sprint is going to hide lol.
If it's not available in all areas, I'd bet they'd hide it. If they officially acknowledge a 3G speed bump in most areas, they would have to field complaints and threats to end service from the areas that didn't.
call and see what happensWell my speed is slower...So should I start complaining?!

I think it's all in your heads
A PRL update isn't going to affect anything unless you roam. Update Profile is just Sprint sending your ip address, username, etc to your phone.
If the update was something else, who knows, but 3g speed increases pretty much would have to be from tower/sprint network upgrades, not something on your phone.
