There's no downside. First of all, the DNS addresses you will be switching to are still Sprint DNS servers that other sprint users have been assigned by default. It seems that different users get assigned different servers and if you're unlucky enough to be stuck with a non-working server this gives you a way to over-ride what Sprint has stuck you with. Secondly, what I describe doesn't modify the original connection parameters, it just creates a new connection with different settings. Switching back to your original settings is as simple as selecting "sprint pcs" from a list (described in greater detail in the instructions).

Thanks pcjoe you rock! I followed your instructions and they worked flawlessly! I also emailed Sprint so that they know about the problem. Thanks again for your excellent solution!!

No big deal really, but you're welcome. Glad to have helped.

Anyone know if there is a fix for a Q9C? I tried changing the dns but it didn't help.

Which DNS servers did you switch to?
