     AT&T and Verizon iPhone 4 owners are more than twice as likely to report dropped calls than Verizon customers, says survey .

    Taken from a group of 4,068 people, the survey's results show 82 percent of Verizon subscribers being "very satisfied" versus 80 percent for AT&T. Those results are similar to an industry-wide, non-iPhone-specific poll conducted separately by ChangeWave. In that poll, 4.6 percent of AT&T subscribers reported dropped calls, compared with 1.4 percent of Verizon customers.
    The figures stand in contrast with quality of service however, specifically in terms of dropped calls.

   Sony chief Sir Howard Stringer may have unintentionally given away plans for an eight-megapixel camera in the iPhone 5. During an interview with the WSJ's Walt Mossberg, he claimed that the company's camera sensor plant in Sendai had seen hit by the Japanese earthquake and that shipments of sensors to Apple would be delayed. Apple has so far only sourced cameras from OmniVision, suggesting that Sony was shipping for a future model.


    Apple might have been eying Sony's new Exmor R camera sensors, as found in the Sony Ericsson Xperia arc , and the recently announced Xperia neo. The 8MP camera sensor there is backlit, which helps it cope with low light situations, similar to what the current 5MP OmniVision

    Boy Genius Report revealed a few leaked photos of the company’s latest evolution of a full touchscreen device, the BlackBerry Monaco / Monza.



     The handset boasts BlackBerry OS 6.1 and users reportedly need a BlackBerry ID to login, which might be tied to other cloud services.

    The Motorola i886 is a very solid candybar phone coated in soft touch paint for a quality feel. It has a 2.2” QVGA display with 262K colors with an ambient light sensor. The display is good enough; smaller text sometimes looks a bit choppy but is readable and the screen can be used in most lighting conditions with little issue. Below it is a traditional 12 key dialpad with navigation cluster. The 5-way directional pad has three buttons to either side. To the left is menu, send and notifications while to the right you’ll find home, end and back. Like most of the phone the keys are painted with soft touch and they have a good feel to them. They are prominently raised and offer good feedback and travel.


 

     Smartphones and big screen sizes are all the rage nowadays and even though they offer great functionality, there is still the casual user, who does not need the big screen and just wants to make a call or send a text. But hey, this does not mean that looks don't matter at all.

     The box of the Samsung C3530 contains a micro USB wall charger, standard 3.5 mm ear buds and the user manual. Nothing surprising save for the lack of a USB cable, which is rather annoying.

    This is a global GSM phone. It can be used with T-Mobile USA and AT&T.


    The design of the Nokia C3 Touch and Type borrows heavily from the higher-end C-series devices as has already been mentioned, especially the Nokia C6-01. Unlike the C6-01 however, the C3 Touch and Type feels extremely well-weighted, solid and reassuringly sturdy in the hand. With a stainless steel finish across the whole unit, it also looks much higher-end than the X3 T&T alternative. The keys are large and visually complement the rest of the phone's aesthetic which is great.
