Hmm ok seems you're right. Like i said in a previous post. the best way to off set that is by creating some Swap space for the device, be that on a MicroSD card or internally, it only needs to be 128mb after all.
Edit: I used to own a HTC G1 and it only had 192mb of ram the Wave has almost 3 times that (well give or take) and the G1 still runs beautifully running gingerbread to this very day the wave should have no problem what so ever!
By the way was the new boot loader access method of any use to you, e.g can you use it to directly boot Android without using Jtag?
jtag tool need first time for initial putting android bootloader.Then i used Odin 1.7 for manipulate with varios firmwares and bootloaders.
