AppleCare Iphone 4 Replacement Testing

Post the first 5 digits of the serial number for each.

The frist 2 are the factory and the last two is the week of the build.

It would be interesting to see if your replacement is older then your original.

 

Neither my original nor my replacement iPhone4 demonstrated any reception issues no matter how hard I tried to replicate the "problem."

 

This is interesting... I have model MC319LL with 86025 and my phone does not exhibit any reception issues no matter how I hold it, with or without a case...

 

Are there different models for different regions?
My serial# starts with 86022 with Model MC605B, and i've had one or two dropped calls but no other problems as yet (jinxed it now though )

 

Hmmmm... Wonder what the deal is with the 7s serial number?? This is the first time I've seen one of this sort. Or have I missed out on something??

 

I wouldn't read much into that, I also have MC319LL and even with a case my signal drops, though not as bad as without.

You know, I've been thinking about this and I have a crackpot theory about this. When apple annouced the iphone4, they said that they had developed a new kind of stainless steel alloy to use as the antenna/support. Now here is my crackpot theory, what if this new alloy is very hard to make, what if even the slightest imperfection will cause the alloy to be more conductive and effect reception? Maybe that is why some people can't get the signal to drop at all (perfect stainless steel batch), why some can get bar to drop but don't lose connection (slight imperfections in stainless steel) and why for some it craps out completely (imperfect stainless steel). Plus this could also explain why there doesn't seem to be any pattern to those havin issue when looking at the model and serial numbers.

That's my crackpot theory and I'm sticking to it.

 

replacement

I called apple @ there 800 number 331 0500, spoke with a supervisor, no replacement, return it to ATT for a refund, or get a case.
What # do u call??????

 

Any charge for overnight shipping? Do you have AppleCare?

 

OP did you order with Apple or ATT?

 

Does the antenna of the new one seem to have any coating or anything on it compared to the old one? Do you get to keep the old one ?

 

IMO they are all the same. I got a replacement sent from Apple Care and I also get on in store, some places I could not recreate signal loss, other places I could.

The antenna design is no different on any Iphone 4 made, so if you are in a low signal area and cover the antenna, bye bye signal.

Seriously, these posts mean well but there really is nothing that will change the design of the Iphone antenna, replacements are the same as new in box.

 

I'm gonna guess and say that 7S will be the new serial # used for iPhone 4 replacements.

 

I was in the same situation as you fred, where my replacement was because of a wiggly home button and a yellowish tinted screen.

My serial number starts with 7S as well, and is a week 26 phone. Everything seems to be working fine for now, but I want to know if 7S is in deed for replacements only..

 

I just got a replacement today - serial 7S026 ....hmmmmm

 

I received a replacement iPhone 4 today due to major internet data problems. My new model # is MC319LL and first 5 of serial number are 82026. It was in a replacement box. Not a brand new box. My old serial ended was 88021 and model was also a MC319LL/A.

I purchased my phone from Bestbuy but thankfully was able to exchange it at Apple.

 

My replacement is not a 7S

I had my iP4 replaced a couple days ago and the serial number has 4S, which is the same as my wife's, which is NOT a replacement but her serial also has 4S. I don't think the serial number is indicating replacement, or at least not that way. Oh yeah, my model # is MC318LL, also the same as my wife's original release day issued iP4.

 

I just got my iPhone yesterday from Best Buy.

Serial #: 82027
Model #MC319LL/A

I definitely get the reception issue here at home. It's most annoying when I'm using wi-fi to browse the internet and fail to notice the reception completely drops out to SEARCHING. . . status. It concerns me because if someone calls I'd be totally oblivious to the fact that they are not getting through. I have yet to buy a case though. I have a Wrapsol kit but have not yet put it on because their is a yellow spot on my screen and I want to give it a few days to go away as was suggested before I waste the Wrapsol on a phone that may be going back for exchange.

 

Same here. I just had mine replaced in a store for syncing issues on the 8th, and it's one of these.
