It looks like HP is getting into the prepaid data game. The company just announced DataPass, a solution that lets you purchase 3G service from your laptop. The service is HP-branded, and that isn't just marketing hype -- the company bought excess spectrum from Sprint and is setting its own prices, effectively turning the PC maker into an MVNO. The no-contract plans start at $5 for a modest 75MB, which HP says is enough for about five hours of use, and stretch up to $30 for 1GB. Look for it as an option across the company's lineup of business notebooks with the Qualcomm Gobi un2400 radio module.
