Ok, zweiter Versuch:
Hi, everyone! This is the piece of hardware I use to read/flash my 599 in conjunction with MTK FlashTools. It is the Serial Cable I knocked up quickly to hook up the phone to PC for flashing (see picture). As serial RS232 port of the PC (COM Port) and phone’s Rx and Tx signals use different voltages, the Max232 chip converts voltages both ways – around 5V for the phone and 12V for COM Port. DO NOT CONNECT YOUR PHONE DIRECTLY TO PC! All these parts (and also 9-pin connector on PC side) are available in any electronic shop for few bucks the whole lot. No shielded wires are needed, if you make wires to PC and to the phone not longer than, say, 1 meter (3 feet).
If this is too difficult for you to make, I can think of another way to do it. Some Samsung and other phones have stock Serial or USB-To-Serial Cables for data transfer. You can use those. USB-to-serial cables allow much higher communication speed (4+ times). Note: widely available from electronic shops USB-To-Serial dongles and cables have 12V voltage at RS232 end – IT MAY COOK YOUR PHONE.
Now the tricky part! Connecting your PHONE to the Serial or USB-to-serial cable! You need to know 3 magic pins on your phone connector – GND, Tx and Rx. 599 pinout I posted earlier, P168 pinout I do not know – please, someone, POST IT HERE FOR OTHERS TO READ! If you made the Serial cable as I described, simply solder GND, Rx and Tx to the suitable phone connector. Apparently, 599’s plug resembles some LG or Samsung. I didn’t even try to find. I have butchered my stock handsfree plug by pulling out and re-inserting pins to required positions. If you use stock phone Serial or USB-to-serial cable, you need to find out where GND, Rx and Tx signals are. Useful link

I hope this answers your questions about hardware needed for modding. The only other way I know of is to buy boxes like Infinity, Xintel etc., costing more than our phones.
UPDATE 1: Even easier DIY hardware solution for flashing. I haven’t tried it personally, but I can’t see any errors in schematics. The following schematics is from some Russian, I guess, electronics wiz. It only uses two transistors for about 20 cents each and can be made by high school student. You can use virtually any small signal NPN transistors like BC337 and any diodes. Do not even worry about a case for it – it all fits on the COM port 9-pin connector. You will need to connect one extra wire to the phone - signal marked POWER on the picture connects to the phone battery (pin 15 or 16 on CECT 599).

Gut das ich das gelesen habe, wollte mir gerade ein neues Kabel braten.
(i hate rapidshare...).
