That being said, GSM Buzz can interfere with your tunes and so "Works with iPhone" speaker systems are required to include shielding against cellular radio-induced static. iHome's new iP99 isn't the only system in the world designed to work with iPhone buzz-free, but it's one of the first to actually ship. iHome's got a reputation for making nice sounding, nice looking, and nicely priced iPod dock/clock radio/sound systems, and at $149 the iP99 looks to be a pretty decent choice for an iPhone-friendly sound system to fit a small room and small budget.
Everyone's favorite airport gadget store Brookstone has a semi-exclusive on the iP99 through the summer, and is currently offering free shipping on the device to anyone willing to pre-order it before the June 1 launch date. Before you pony up that $149, you should also know about the Logic3 i-Station Traveler ($60) and Altec Lansing T612 ($199), both of which are also Works with iPhone speaker docks.
