Syncing two iTunes libraries to one iPhone?

I have an iPhone 4 and use two different computers with separate iTunes accounts on them.

One is a Mac from which I get my photos from (using iPhoto) and the other is a PC which I get my music from.

I also make movies (using iMovie on the Mac) and would like to get them onto my phone. However, my phone's "home" iTunes account is apparently the one on the PC. The movies I make in iMovie have been imported into iTunes on the Mac and are in the Movies section.

When I hook my phone up to the Mac and try syncing movies onto the phone, a message pops up and says "The iPhone "iPhone" is synced with another iTunes library. Do you want to erase this iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."

Is there any possible way I can sync both iTunes libraries onto one iPhone? I don't want to delete the music from the PC's iTunes and want to put movies from the Mac's iTunes. What should I do?

[I've also tried e-mailing the movies to my phone but I don't ever receive the e-mails. I check the Outbox on the Mac and it says "This message has no content."]

When will Sprint restock Iphone 5s?

Well I was put an a waiting list as #42 I was really confident I was going to get the Iphone 5 I thought I'd be #300 or something so I was glad I was such a low number but turns out the store and all other stores only received about like 10 Iphone 5s or something. I'm confused I'd think they'd get a ton but besides that I'm wondering when will and how soon will any Sprint store restock on more Iphones anyways? Will the next time they restock be still a low amount or higher? I have looked and called everywhere and nothing. Thank you please answer my question I appreciate it completely

Does the iPhone 5 really come with 16gb of internal mem?

I heard that the 16gb version of iPhone 5 only had 5gb internally. Is this true? Or only for AT&T users. I have a verizon plan, not to worry about caps and limits, I just want to know how much internal mem the16gb comes with. If it's Really 16 gb, then fine, but I'd like to, (if possible) hear from a person who bought the 16gb version. I decided the S3 is too ugly and chose the iPhone 5, just wanting to know if I should waste a 100$ to get at least 16gb.
