On my EVO, my TWS (TIme without signal) is usually over 90%. From what I understand, this is VERY high. Some blame the GSM-CDMA trick for this, but I'm not sold. Granted, I have a bad signal in my house due to all the electronics from my home office. BUT, I called Sprint and talked to them and they're solution was the following: They're sending me a free AIRAVE with free service for a year. ($5 month after that, but I'm sure that could be negotiated when the time comes This boosts 2G signal ONLY. However, the tech said to use wi-fi, turn 3G off and that should solve my high TWS. Not a bad solution IMO, but I'll update with a review when I get it in about a week. NOTES You have to be firm, they started at the usual price with free service, but after a few call backs and re-routes, I got it down to $25 with a $30 credit when it comes. Service is usually $5 per month, and they said it WILL be after a year, but I'm pretty convincing when I need to be. They are currently back-ordered, so 7-10 days until it ships. If you have poor service in your area, they will usually not think twice about doing this, but my service is excellent here besides my house which is a total dead zone. Cheers!
