Apple hoped its recent press conference could heal the bruising the iPhone 4's image has taken from the press. But for further repair there's Antenn-aid, a vinyl Band-Aid sticker sized precisely to cover your iPhone 4's antenna gap. It's mainly a gag, but if you're trying to avoid a bulky rubber bumper, you might give it a shot!follow link
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
