One of the big features that has been added to the iPhone 3G and iPhone 3G S has been tethering. This is where you connect your laptop (I was tempted to say MacBook) to your iPhone and use the iPhone as a modem to connect to the Internet.

I have to ask WHY??

I can understand the need to access the Internet wirelessly while you are out and about but why use the iPhone. There are some great deals right now where you can get USB stick modems for next to nothing (or just paying postage) and you can get a PAYG 3G SIM and get wireless access for about £2.00 a day or £10 a month. This is as cheap or cheaper than tethering your iPhone and you are not using any of your “unlimited” allowance.

If you think that is too expensive then why not just get a USB stick modem and put your iPhone SIM in it. Configure the APN correctly and you are online for no additional charge. It works great with my O2 iPhone SIM. OK you can’t take calls while you are using it but you can still send and receive Text Messages, and there is no hassle about paying extra for tethering.
