sprint hero crashing, need help or ideas lol

[mattatat]

so let me start by stating the problem, and ill post things ive done to try to fix it lol... any help, or ideas are greatly appreciated.

bought a sprint hero, originally came with 1.5 i think... was upgraded to 2.1 at a sprint store late june or early july. i havent flashed anthing other stan stock roms. the problem started after upgrading to 2.1... i think lol. the problem is that when you try and run either google maps or sprint nav, they kinda half open and then the phone soft resets itself. after the phone powers back on, if you try and open the app, it will continue to soft reset itself.

ive hard reset. google maps/sprint nav will work fine for a couple of weeks and then the problem starts again.

sprint has sent me a new hero... worked fine for a few weeks, then started doin it again...

ive spent long hours on the phone with sprint tech support, and advanced tech support, and theyve never heard of the issue. ive searched here and at xda for problems like this, and have found zero threads/posts describing anything even close..

i hard reset the new hero, and didnt update any of the apps thinking that maybe one of the updates caused the problem... same time span.... bout two weeks, it soft resets itself...

i downgraded to the 2.27.651.5 build and rooted, removed a few of the bloatware apps (from the list of safe to remove apps on here) and its been about a week, and last night just checking to see if it happened or not, started google maps and it soft reset itself...

the phone works fine otherwise... at this point, sprint told me that theyve sent me two phones and that i need to take it to a store and have it looked at by the tech... so i know i have to flash back to unrooted stock and wait for it to start happening again so they can look at it.

anyone else have this problem, or hear of a problem like this?
