internet help

HELP - my Sprint Mogul is SLOW, SLOW, SLOW for the past 24 hours to basically render it useless for internet and email. Any suggestions. I have the Feb 2008 ROM - didn't feel the need to update since my phone was working just the way I wanted except for the last 24 hours. The only change was just about an hour ago to up date to the latest PRL ...14, was ...10. No difference. And, also my tethering with PDANet is unusable too - what gives, any suggestions. I had my phone tested at the repair center and the "dunce" there said I had too little memory - HECK, I had 19mb FREE!!! when I can normally run with just 5mb of memory. Idiot! I not thinking a hard reset will work - sooooo PLEASE, any suggestions. I use my phone a ton on the road and everywhere in between. Thanks.
