Yeah, it was a pain in the ass going to all Claro stores in SPS. On one occasion, when I asked first if they had, they said yes (even showed me one), but said I had to wait my turn. After waiting for about 10 minutes, it's finally my turn, and the woman told me "I'm sorry, but the system is down". F... you!!! Why didn't you told me from the beggining! or when you saw me sitting there waiting!!! Man, I was pissed... I have been Claro's customer for more than 3 years, but this made me think of switching to Tigo...
Well, I went to the Progreso store, cause I work in Progreso, and the store was empty. I asked about the iPhone, they said they had it, and had to go through again them explaining the plans and stuff... it took about 30 minutes or so. And when I got to go to the cashier window to pay up, the cashier sees me with the credit card on my hand and says "Oh, but the credit card system is not working right now." WTF!! I was starting to think that God just did not want me to get the iPhone... and I had already signed the freaking 2 year contract... and I did not have enough cash for paying for everything (oh, BTW, they charge an additional 90$ for and "insurance" deposit, that they said that it was in case I missed a payment).
So the cashier looks at me, sees that I'm about to start yelling at her and says "Give me the card, I'll try to pass it". And lo and behold, the card passed (it was the most satisfying "beep" I heard in my life). And they gave the phone, but I had to wait till the next day to use it because the person responsible for activating the iPhone was not in the store that day. But I thought, what's an additional day if I had waited several months for this. And it worked all right the next day.
About the iTunes app store, from another forum I got the tip to use the El Salvador store, and put my credit card, and use any state. And it worked all right. My iPhone is already full of crappy apps. Just kidding, some apps are really good, I recommend the Midomi program, it is great.
Sorry for the long post, but that is the long adventure I had to endure to get one of these. And I must say, I love it.
Hopes this helps.
