CUPERTINO, Calif. ( TheStreet) -- The iPad hits the market this week, prompting many small-business owners to wonder if it's worth changing cell service providers to get a hot new mobile device.Earlier this week, Apple ( AAPL) shipped its cool, uber-hyped tablet computer. So how do you connect it? While the wi-fi-only units start at $499, the more robust wi-fi and mobile network iPad will run you $630, with data plans from AT&T ( T) starting $15 per month. If only it were that simple. Verizon ( VZ) and Sprint Nextel ( S) offer mobile hotspots that will enable the iPad to connect to the Web. And gadgets from companies such as Cradlepoint can take most cell data modems -- even those from T-Mobile and Virgin Mobile -- and turn those into wi-fi hotspots that an iPad can detect. In theory, any provider can support the iPad. But you never know if something will work until you try it. And Apple has a strict -- and lame -- 14-day return policy. To be sure your sexy new iPad works, you'll need to quickly carve out time to test your connectivity. And if it doesn't work, take that sucker back. With those limits in mind, here is our Spring 2010 Mobile Data Access Round-Up: Sprint Mobile Broadband Connection Plan 3G/4G: $60 per month for 5 gigabytes of data use for its third-generation (3G) network and unlimited for its fourth-generation (4G) network. If you are looking for a mind-boggling wireless experience for the iPad -- or any wi-fi device -- pick Sprint. For now, the company is America's only real 4G data provider. We have tested the 4G and 3G versions of this network across the country and found the 4G access dazzling and the 3G service stable and flexible. Sprint says 120 million users will have access to its 4G network by year's end, including customers in Los Angeles and Miami. All this may change when Verzion and AT&T roll out their 4G networks later this year. But for now, cellular data access is Sprint's game to lose.
