I've recently got a N73 on Three - and I'm using the X-Series plan which gives me unlimited (with limits.. go figure) access to MSN, Skype and.. other things.
I'm sorry to report that this phone is really quite buggy.
I know there are methods to upgrade the firmware yourself, however it's unclear to me the risks involved. Have a read of my currently unanswered post on allaboutsymbian.com
Here's my mail to 3 - I'll update if/when they reply
Hi -
I've recently got a N73 from you, and it's amazingly buggy. It
occasionally will crash when I answer calls, sometimes reboots, often
tells me I don't have enough memory and should close some applications.
Not very usable at all. My phone shop is going to replace my handset,
but I'm almost certain this is related to the Firmware you use.
My N73 is running v2.0628.0.0.1, which is a known buggy version of the
Nokia firmware.
If you look at this site, it shows a list of bugs:

Notice here that in the firmware you are currently using it has a memory
leak in gallery (would explain my out of memory errors), frequent
reboots, applications not closing properly and more.
When will you be updating your firmware to the latest Nokia release so I
can have a phone which doesn't require rebooting every few days of usage?
Many Thanks,
