Matrix Infinity different versions?

[fratres]

A modchip-installer told me Matrix Infinity have different versions with different coulored stickers on top of the Actel, and that just the ones with turquoise stickers are working in the PSTwo. Is that true? On the Matrix site I only saw pictures of chips with orange stickers, so maybe he is wrong? Is every Infinty working in the PSTwo? I am planning to mod my V3, but as I am not sure if the laser lasts long (does read DVD+R, but sometimes has problems with straight boot of originals) I would like to get a chip that works for the PSTwo as well, so I can get one when my V3 dies. And do you think someone without soldering experiences could install the chip in the V3 (probably not after the first coffee in the morning), saw very good guides and pictures, but the spots look so damn small. No chance?
