fxit_man - i must say for the record that you are a legend and i would love to see how pimped your iphone is hehe
Haha thanks man! You'd actually be suprised how
un-"pimped" my phone is

Theres a lot of people here that know a lot more than i do though!
Still dont really understand the difference between Cydia, AppStore and Installer? Do i still continue to download from installer (does anyone know of the good sources?)
Cydia - Similar to Installer, but since the release of firmware 2.X, it has become more popular than Installer, simply due to the fact that it was ported over to firmware 2.X before Installer was. It does the same thing as installer, but for me and many others im sure, it is much more stable than Installer so i tend to use this more. In fact i hardly ever use Installer.
Installer - Ported over to 2.X
after Cydia, therefore it is somewhat
less popular. Does the same thing (provides third party apps to "jailbroken" (hacked) phones.
AppStore - Official Application Store from Apple which sells Applications and Games (some free, the good ones at a price). Downloading from here wont stop your iPhone from working in any way. They tend to be more stable than the releases from Cydia and Installer though (from my experience) as the developers are charging a price (for the good ones anyways) , the developers include famous publishers such as 'Vivendi' and 'Polarbit' who are responsible for Crash Nitro Kart 3D and the applications are created with the iPhone SDK - a tool from Apple themselves. A "software" iPhone to test applications on before releasing to the public.
1) What the hell is this SSH and SSL you always speak about?
2) Does bluetooth not work at all? I can get it to sync with my garmin gps? but today i got it to work with plantronics headset which was cool
To answer your questions:
1) -
SSH (Secure Shell) is a protocol for creating a secure connection between two computers. In this case, a protocol for creating a connection (wireless) between our iPhone and our PC..
We use a program such as
WinSCP to do this, after installing "
OpenSSH" on our iPhones which we can find in Cydia/Installer.
It is useful to do stuff such as :
Replacing system files, transferring custom ringtones to the iPhone, setting permissions for folders on the iPhone etc.
SSL (Secure Sockets Layer). A cryptographic protocol that provides secure communication via HTTP. There is a setting in the email settings of the iPhone to turn SSL off.. That usually fixes any errors i get with my email account not working.
2) Bluetooth
does work on the iPhone, just not for transferring files. So you should be able to connect it to your Bluetooth enabled car or connect it to an iPhone compatible headset.
Hope that clears up things a bit for you. These are very basic descriptions, but should give you a basic idea of what each thing is.
P.S Welcome to the forum.
