I've had my Omnia for some time now and have noticed that in an 8 hr day of work w/ mostly texting and internet talking is at a minimal. Not really played with the setting to conserve power, I know adjusting the backlight is a viable option for most phones like these, and Wi-Fi is off since I have Rev A. in the area.
Now the real annoyance is over the last few days I've noticed my text alerts are not working 100% of the time, If I power cycle it will for for awhile then drop to working iffy or not at all. I've tried diffrent alert tones and the same result on them. These are MP3 tones I d/led because I didn't really care for the defult ones

Has anyone experianced this problem?
