Ev keeps dropping to 1x?

[CaliBoyPhillip]

I live near the LA county and my signal show fine as ev but now jsut around 2 weeks ago or less when ever i try to use data app's like let's say opera, IM+ or so on.... my signal drops to 1x and then back to ev then after a while back to 1x so has anyone else been exp this issue daily? I'm thinking of just calling sprint and tell them as I've been having this issue far to long and yes I've tried flashing to shipped and hard reset lol and update data and blah blah as I've given out those tips to others before ;] so any help will be much loved! oh yeah and to mention before this wasn't a issue so it can't be low or weak signal or dead zone as I normally have 2 bars to 3 or much more depending and still drops to 1x.
