With the 3.0 iPhone OS, new baseband, and everything, there are several problems floating about. First, there are a large handful of users plagued by the rapid battery drain problem. How do you know if you have this problem? Well, its quite simple actually. Before upgrading to 3.0, your battery is good for 12 hours, 8 hours, whatever. After upgrading to 3.0, it discharges even if you have the phone plugged in, and you're generally looking at no more than 3 hours idle time. Second, if you hacktivate your iPhone, you don't get youtube and you don't get push notifications.
I've found that the battery depletion problem is usually to do with activating using an official SIM, and then hacktivating the device, because apparently it leaves some messed up APN settings on the phone. As for the push notifications, hacktivating it directly is not going to work because you're not going to get the certificates required for push notification.
Luckily for me, having an official SIM card and a third party SIM card means I can have the best of both worlds, and not have to worry about either problems. Unfortunately, though, it does mean restoring the phone is a bit more time consuming.
Now, I must note that this is a memo for myself, and nothing but. Don't complain if you do not have an official SIM card so you cannot get it to work. Don't ask me for my certificates, because I don't want to share my pushed email messages and risk getting banned. With that said, let's start.

iPhone, while great as is, lacks some very useful features. For server administrator / developers such as myself, the ability to access SSH to monitor my server while I'm on the go is a must. However, up until very recently, this was not possible. Well, that is no more.
Three weeks into my iPhone 3G, and I must say, it is still acting like an overly glorified iPod Touch...
