Last October Fidelity offered me a card - which I really had no need for, but it was all but approved because of my stock account, so I accepted. Opened with a "useless" $2000 credit limit, so I sock drawered it from the get go and never used it (BoA and I don't see eye to eye, even though this is FIA). I've been getting notices on the new Fidelity Signature Visa and I was wondering if ELAN (US Bank) would issue a "Signature" with a $2000 CL, but today the request a credit limit increase option showed up on my account. Asked what I was requesting and I said $10,000 figuring it would be declined - Boom approved $10k. This card was on my close list for next fall "thinning" due to the low limit and I have other 2-3-5% cards, guess that's not going to happen now.
Interesting thing, I closed my Barclay's Apple Visa 9.5k CL and my eBates Visa $10k CL last week as part of my thinning, in the last couple of days my Chase Freedom Unlimited went from $3.5k to $10k and my Fidelity went from 2k to $10k, so in fact the "loss" of available credit is next to nothing - funny how things work out. 
Nice, Congrats
Very cool! I've been thinking of getting rid of a couple of cards as well. Congratulations!
