AT&T today announced that its shared data plans will be available starting August 23rd. The company also introduced a new web tool to help users pick the correct plan and estimate costs. AT&T first announced the plans on July 18. Verizon started offering its shared plans in June.
Just a small FYI...Ralph De La Vega spoke to shared data plans last year at CES when he announced the first Atrix 4g phone. So, this has been in the works for years from both companies. Not really a sudden thing.
