Leonard of PocketPCTechs.com informed me, that there is a review posted, over at
HowardForums, about the previously announced 128 MB RAM update for the HTC Magician (i-mate JAM).
Here's a review of our i-mate JAM 64 MB to 128 MB internal RAM upgrade
done by Mark Morrow and posted on HowardForums. It is very well done and thorough. We also took some photos of the process which can help in explaining why the upgrade costs what it does and why it is not user installable.
You'll notice the old chips laying upside down, next to the
PCBA. These are Ball Grid Array (BGA) chips which instead of having metal
leads coming out the side of the chip that you solder onto the motherboard,
there are little solder balls that are underneath the chip. We use
specialized equipment to align and then reflow the chips onto the
motherboard. Definitely not something for the end-user to do.
So if you already have an i-mate JAM or plan to buy one (for example from PPCW.Net) and the original 64 MB aren't enough for you, you should check the article.
