Bone up on all the solutions for connectivity.
Save as txt or offline webpages onto your 770 sd card
all the possible solutions to dealing with wifi issues on the 770.
THEN go to McDonalds.
Then you can troubleshoot what you need to there ...if necessary....
without needing wifi access you can't get from your 770 if it has connectivity issues.
In other words.
Don't show up at McDonalds with no solutions to try.
It'll make for a short trip and disappointment.
In even other words ...
It means you got some homework to do tonite before going to McDonalds tomorrow.

"Bless you my son" ?
really?
I'm guessing I'm much older than you and it should be the other way around...or you are a priest ...(in which case I most assuredly will burn for my insolence..)
either way...
You're welcome...
No worries dad...

At 72, almost everyone else is a kid to me.

hahahaa....
well then you are old enough.
whew!
well that's better than burning in hell because I was cheeky to a priest!

Best advice I can give at the moment is...
don't eat the bacon.

non-Mcdonalds advice...
considering you got your device up to 2007 hacker edition so effortlessly...
I highly suggest going all the way and getting 2008 hacker running...
it is a little more intensive...but well worth the effort...since it means "almost" compatibility with the n800/n810 line of apps.
Making it on par almost with them.

I do suggest finding a used n800 and / or an n810...
you will find them much easier, more powerful and more enjoyable to use...as well as way more applications that you can play with.

Just won this:

I love toys, especially when the price has dropped to almost nothing. I still program from home and support oil & gas projects via the internet. The N800 looks interesting.

Well that was bizarre.
Power outage while I was writing .
Put me in the dark for the night.
Candles fireplace and my n800 with a nice cup of hot chocolate.
Not a bad way to spend a chilly night.

Oh my yes the n800 is interesting...
You'll love your n800.
I suggest the links in my signature for starters.
You'll still love your n770
but you will probably end up using it as a book reader or perhaps for music ....the n800 will end up weaseling it's way into your heart more and more.

Is there any advantage of the N810 over the N800?

The N810 has a hardware keyboard and GPS, while the N800 has FM-radio. Otherwise the specs are the same.

Do the 770, N800 and N810 use different chargers?

Thanks

Sorry been out most of the day...
yeah what he said
n810 keyboard and pain-in-the-butt gps and only 1 sd card slot
n800 fm, no keyboard, no gps, 2 sd card slots
Both are great devices in their own.
the n810 keyboard is one of the finest I've ever used.
the casing is well done too for the n810.
The n800 is grand with the 2 slots...excellent for putting multiple os's on it. Grand for running the system off the internal card slot and having all your stuff on cards for the external card slot.
No built in keyboard...there is always usb, there is bt keyboards, ir keyboards...lots of option there. So it isn't a detriment ...I have a few diff keyboards...cheapest one is a hand held bt keyboard for 5 bucks from china...works great.
I have a few of both the n800 and n810...
I couldn't choose if I was told to.

Both the n800 and n810 use the same adapter...
I suggest the more block like travel adapter ...and I suggest getting 2 ...one as a back up.

Battery types between the two are different though.
I suggest a minimum of 4 batteries for any of the models.
that way you have one you run into the ground as a plugged in all the timer.
2 as your travel batts
and one as back up
always store in a cool dry place.
Some have stored in fridge or freezer with good extension to lifespan.
Make sure any stored batt is sitting at roughly a 66% charge.
Don't store with a low charge nor a full charge.
