Ask HN: Tips to find an iOS developer position *starting in 3 months*?

I'll be graduating in 3 months and I want to work as an iOS developer. I have one app in the App Store I published with Stanford, and I will have another app published shortly with an open-source company as part of GSoC 2013. I have a 3-months head start in my job hunt, and I've already started getting in touch with companies, but most of them are looking for immediate hires. Any tips on how to improve my chances of finding good opportunities?
