Just switched our corporate plan from sprint/nextel to AT&T. We pay alittle more (maybe $200 a month) with AT&T but at least we get better service now, and can put our issues with sprint/nextel behind us. Got so bad at the end with sprint/nextel that they couldn't even activate their own phones they shipped us. AT&T has also given us a ton of perks included (roadside, ptt, insurance, free phones, no activation fees, etc) as part of our package and is giving us about 15,000 mins more a month, so it has been worth the extra money... so far.
