is there's any negative thing by doing this other than the battery life. and how can i force EVDO. thanx in advance

Not really sure how to force EVDO but the reason your device is switching to 1X when receiving a call or SMS is because it is incapable of receiving the SMS or calls on the EVDO.

To the best of my knowledge anyway...

Yes, if you force EVDO (which you can do), you'll be unable to make/receive calls and use SMS, because they both use 1xRTT only.

When I forced evdo on my touch it caused my sms to only send and receive whenever I placed a phone call, which I was still capable of doing. I didnt receive any phone calls though; it is possible that nobody called me that day.

My home area Sprint did not have evdo until a couple of weeks ago (Yay me) I would hit evdo every now and then I could force my phone to evdo by selecting roaming only sometimes it worked sometimes not it was hit and miss
