I'm curious for your reasoning on having to put in $75? It is a factory unlocked 32GB iPhone 4 which is going for comparable money on eBay and I see similar offers on CL.
Ur iPhone 4 is most likely more than 2 years old. Batteries degrade over time. It's way out of warranty. If something else goes wrong it may cost $150 to swap it out.
You can still get almost any att iPhone unlocked for $10 from various sites (even though its "illegal to unlock phones now without carrier consent"
iPad mini has at least 8-9 months of warranty left. It's still a "hot product"
You might find some suckers on Craigslist willing to pay you $300 for your 32gb iphone 4. There are suckers on Craigslist.
Honestly since I am a savvy buyer. I wouldn't pay more than $240-250 for an iPhone 4 32gb mint condition 2 year old phone.
iPad mini 16gb is still worth at least $300 on resale market.
That's why they said u need to throw in some money along with your iPhone 4.
Remember iPhone 4 is single core and iPad mini is duo core. Big jump in performance from single to duo core also.
Depends on a sucker you can find to do an even swap.
I live in Orlando area and right now can get a mint condition 32gb iPhone 4 unlocked for $250 or less (multiple listings) which means I can probably get someone down to $230 easily. Of course you got people listing for $300-400. Those will never sell at those prices.

These are the completed eBay listings for iPhone 4 32gb ATT.
Average selling price is around $250-270. Factor in eBay fees. You are looking at a net of around $250 max for your iPhone unless you want to risk selling it internationally.
