iPhone Performance with Lots of Contacts ...

So I know I keep a lot of contacts on my phone. I don't WANT to, and I certainly don't NEED to have it sync the entire contacts folder of my Exchange server. But really, I have little choice since Apple still refuses to add a feature that lets you select which folders or contacts to sync from Exchange. Until that happens, I'm stuck with just a bit over 4,300 contacts on my iPhone.

It. Crawls. Like. You. Can't. Imagine.

Even something as simple as typing a name into the recipient field of a new text message will take 15 seconds just show the first letter I've pushed, and almost as long for each subsequent letter. Even after I type in the whole name or number, it will take up to an additional 30-40 seconds to find it in Contacts and show it in the list.

Looking up contacts by scrolling the letter bar in the Contacts app or through the Phone's integrated contacts lookup is an exercise in sheer futility. It. Takes. Forever.

Addressing emails are bad too, even if slightly faster than the others.

I love my iPhone, but if I can't find a way around this, I'll have to find another phone that has better performance OR at the least lets me decide what contacts get syncd and which ones don't. What's not an option for me is to unload the majority of my contacts into a Salesforce CRM database or something and keep a smaller subset in my Exchange account.

I'm using an iPhone 3G with OS 3.1.2. On my exchange server, I have the 414 contacts I really NEED to have on my iPhone in the primary Contacts folder. I have subfolders of Contacts for different purposes which contain the remaining 3700 or so contacts. They don't need to be sync'd to my iPhone, but do need to remain in their folders on the Exchange server.

I can't be alone out here on this one...surely others have had similar experiences if they keep large numbers of contacts in their Exchange folders...? Anyone have any suggestions or ideas to offer? I'm growing desperate.
