(con't)

Here's what you would need to do to get where I am with my internet tablet:

-Install the high-speed 48 MHz bus version of fanoush's excellent, excellent alternative SDHC kernel. The 770 is capable of running the bus between the CPU and its MMC card at 48 MHz, but by default it runs at 12 MHz. Installing fanoush's recompiled kernel running with a 48 MHz bus increases the transfer rate from ~1 MB/s to ~ 4 MB/s. Nice! The only downside is that your card might not work if it's not up to spec. Worst that could happen is data corruption and losing your files and the operating system, but that hasn't happened to me yet, and I bought some crappy no-name card off of eBay from someone in Hong Kong.
-Then, boot from the external MMC card (I'm using ext3 formatted, certain guides recommend ext2 but I haven't noticed any significant performance penalty with ext3). Normally the 770's OS is stored in the device's flash memory. Since that memory is only 64 MB (128 total, 64 for the system), however, the file system runs compressed, which takes up a lot of the puny CPU's power. Now, if you were to install the default OS on the MMC card it would run just as slow since although it runs uncompressed it also runs at 1 MB/s, but with fanoush's new kernel it runs far faster.
-Install the wifi driver patch that everyone's talking about.
-Install Canola 2 and the YouTube plugin. That'll give you YouTube goodness.
-Install the minimo browser engine and use that instead of Opera. It runs slowly on the default install, but, again, with fanoush's kernel and when running off of MMC it runs just fine.
-Activate swap space through the control panel. This effectively increases your RAM from 64 MB to 128 MB.
-Use OS2006. Don't even bother with OS2007HE (OS2007 Hacker Edition). If you want the latest and greatest, shell out the money for the n800. I know a lot of people use 2007HE, but there are always small bugs in it that just kill the joy for me, like the cover not working properly when you close it. Besides, it's all about OS2008 now, which the 770 can't run at all (there is an OS2008 Hacker Edition for the 770, but it's really awful.)

Here are the drawbacks of these "hacks":

-No official support. I'm not sure if Nokia has any kind of support at all for the 770 anymore, but whatever they might have or some third party might be providing you with (such as under a support plan), don't expect anything when you're running this software. But, then again, the 770 probably isn't supported by anyone anymore anyway.
-Possibility of some instability. I haven't had any problems yet, but with the 48 MHz patch ostensibly there's a reason why Nokia didn't set their kernel to that bus speed. YMMV.
-Can't take the MMC card out during operation. I'm not sure if anyone has regularly used this "feature", but with the default install if you're not using any swap space you can actually take the MMC card out whenever you want. Obviously if you're running the OS off of the card, however, taking it out would be a very bad idea. But who used that functionality anyway? Besides, for the tablet to be even remotely runnable with any modicum of comfort requires swap space even when using the default OS2006 install, which doesn't allow you to hot-swap the MMC card.

I hope that helps anyone still considering buying one of these things. Right now they run $70-$80 used on eBay, which is a steal for what they can do. Throw in a bluetooth keyboard, a bigger MMC card, and USB accessories for accessing your USB gadgets and we're talking $180-$200 total.
