Not with an iPhone for tethering you can't, and it is also much slower.
The Netgear N versions are not bad at about £30, but if you are going to have to use a dongle, why not just use the iPhone USB cable? Most modern laptops should have wireless built in, however basic it is.
Now I only used WI-FI dongles, and have three 7.2Mbps, one on contract and the others on £10 per gig prepayment all from T mobile and here in Wales find them bloody wonderfull, I don't spend enough time in my house to make it worth having a landline so I only use a mobile and WI-FI so I can be totally mobile
Thanks chaps. What i was trying to achieve was doing away with having to tether it every time i wanted to download a big app. I have wired net connection anyway so was trying the wireless route. Guess i'll stick to the tethered option or wait until i go somewhere where they offer free wi-fi like Mc d's or the like
I think this-IEEE 802.11B/G Wireless WIFI Dongle Bridge, maybe can help you. It can operate with any ethernet-enabled devices, such as desktop computer, network printer, laptop computer, Router, ADSL, or a security camera. It is operating system independent and can be used with any Microsoft Windows, Linux or MAC OS operating system.
