Best thing to do. Make yourself a word document with all of your contacts. Might take some time but will save you in the long run if anything was to ever happen.
I have a hard time imagining contacts consuming enough internal memory to be even remotely problematic. I could be wrong of course, and I run the 8330 ,anybody confirm how much kb usage your contacts actually consume???

I have well over 1700 contacts in my address book with a lot of additional information (home number, business number, email, contact, etc.) without any problem.
Also I have about 7 additional apps installed, about an average of 200 appointments on file, run VIIGO, run TodoMatrix and run Pocketday constantly and still have 24251652 free memory.
The least you can do is sync with outlook and / or make often a backup. This way you don't have to worry about data loss.
Looking at the Advanced tab after a Backup will give you the size of the Address Book database. These are never very large.
If you consider 1000 characters per entry, which is a lot (the line below is 100 characters) when you are thinking about names and adresses, phone numbers, emails, etc..
12345678901234567890123456789012345678901234567890 12345678901234567890123456789012345678901234567890
Let is now assume that you have 1000 entries so 1000 x 1000 = 1million or slightly less than a megabyte (1024 x 1000).
So 2000 entries is a bit less than 2Mb.
This is not even worth thinking about.
Delete the BlackBerry Sample Video and you get more memory back than this.

I have 962 entries in my address book. It occupies 186kb. An insignificant use of memory, but it does serve to corroborate Pete's worst-case estimate.
I just picked 1000 bytes as an easy to use number. I said that it was a lot to allocate per record and JeffH's number confirms this. If we look at JeffH's numbers, we get
186Kb or 1024 x 186 = 190464 bytes divided by 962 entries = 197.98 characters (bytes) per Address Book entry.
So my original number was out by a factor of 5 (well done Pete6) but I was not trying to be accurate, merly demonstrating the small size of the problem.
What is now clear is that from JeffH's numbers we can assume that the average Address Book entry takes up 200 bytes or characters of space.
This number will depend upon what data you have and if you have two full addresses, multiple phone and email entries as well as lots of notes on each entry then this average will rise but probably never above 500 bytes per entry. There will also be a minimum number of bytes even for the entries that have just a first name and a single phone number. This is because there is a small constant overhead attached to making any database entry.
Either way, the amount of data occupied by the Address Book is insigificantly small and will never seriously impinge upon memory statistics.
Another way the question is sometimes asked is, "How many phone numbers can my BlackBerry hold?"
Assume the user has performed Reed's Memory Optimization procedure and has 22 000 000 bytes free. Subtract the 12 000 000 bytes minimum that you have to keep. That leaves 10 000 000 bytes. If you allocate it all to addresses, and use 200 to 500 bytes/entry as typical and worst cases, then the answer is at least 20 000 to 50 000 address book entries.
With 10,000 contacts in the phone it sorts through them with a breeze. We are having some other wierd things happen that we are trying to see if the memory usage is affecting and will update this post when we know more. It would be great to move them to the memory card though and I thought they said it was possible when I was speaking to Verizon. I am calling them back to find out.
