Apple's iPhone 4 made its debut to long line of shoppers last week. We already knew that the new iPhone was popular, as pre-orders sold out on the first day of availability, but now we're getting an idea of just how many iPhones were sold.
Oppenheimer's Yair Reiner estimates that Apple sold 1.5 million iPhone 4s on launch day alone. That's one and half times as many iPhone as Apple sold over three days in 2009 and 2008.
It also seems that many of those buying new iPhone 4 handsets were repeat customers. Piper Jaffray's Gene Munster says that 77 percent of iPhone 4s were sold to upgraders who already owned a previous version of the iPhone.
But not everyone was happy with their new purchase, as reports suggest that many iPhone 4 owners experienced problems with cellular reception on the phones. Many people found out that they experienced interference with calls and data service when they put their hands on the phone's lower-left corner.
Apple specifically designed the iPhone with the antenna built into the steel frame that surrounds the phone, saying it would improve reception. Now the company is telling iPhone 4 owners that they should avoid holding the phone by the lower left corner.

After reading an article on the subject, the problem has been introduced to an iPhone 3GS which has been upgraded to OS 4. This indicates it is possibly a software issue (or a combination of both) In it’s hard case the issue does not occur.
I bought a iPhone 4 and had the same problem so I got a case for it and now have the best reception of any cell phone that I have owned and I probably have own about 15 or more
i upgraded from a q9m by motorola, only had about two dropped calls over a period of a year or more. i got the iphone4, (verizon). i’ve had it for about a month and so far i’ve lost over a dozen calls and are being laughed at about my new fone. i think apple should fix the antenna problem instead of teaching us “how to hold the fone” we know how to HOLD a fone! i’m hurt and very upset.
