Upgrading RAM.....

This might be going too far, but I am surprised I haven't heard of someone or some company upgrading the RAM on like the Mogul or Touch. I know they are soldered onto the board, but they are actually soldered, not hard wired so it shouldn't be too hard. Anyone know of anything like this?

Ok its my understanding that this is not an option because it is "Part of" the PCB not simply soldered on. These devices dont use RAM "Banks" like a PC, instead due to the size of the pcb are integrated with the ROM chip on the PCB.

I saw a link to a company that had looked into doing this for various PPC phones, I don't remember the company but I think the link was posted at the XDA forums. They didn't give any reasoning but the site said the upgrade wasn't possible.

Cool. I am actually a Sprint Tech (Posting from work) and I know that on the Mogul it is just a small chip soldered onto the board. I have no clue though on the Touch.

It could actually go down into the MB wafer, but it has actual solder drops on the top of it, not hardwire. The truth is though that if it was easy to do, we would probably already be seeing it. Thanks for your help!

I too am a tech

these days i simply consult with SPCS and no longer deal with the retail channel (i worked on 2 service center roll out projects, 1 w/PBW - now ATT and we developed the Nextel - now SPCS program). My local MM and I go way back almost 15 years (we both worked for long dead USWest/GTE Mobilnet and then Wcom).

Companies used to promote this for the Apache and other models. As you know from looking at the Titan PCB its really not an easy and or reliable mod unless you are seriously advanced. I have some experience designing PCBs and you can get into trouble real fast working with such small real estate.

One of the problems with upgrading the RAM is the warranty issue. If you have TEP, I suppose you could say you lost it and pay $50 for a replacement. However, this is unethical. In addition the cost would be a couple hundred dollars for the upgrade if it was possible (from what I remember reading a while back on XDA).
