Mr. Nguyen Van Cuong (District 4, Ho Chi Minh City) bought a black iPhone 4 32 GB from an online seller.

Refurbished iPhone 4 is made from new case, accessories, and sophisticated box printing.

According to Mr. Quoc Thang, a technician at a store on Vo Van Tan Street (District 3), the `rebuilt` iPhone 4 appearing on the market is not new.

On online sales sites, classified ads such as selling new iPhone 4 with 100% new capacity of 16 GB and 32 GB appear a lot.

An Apple seller in Phu Nhuan district, Ho Chi Minh City, said that the refurbished high-capacity iPhone 4 line is being smuggled into Vietnam from China `in full swing` since Tet.

`The way to turn an old iPhone into a new one is not strange. A large part of the smartphone lines floating in the portable market from Android, Windows Phone to iPhone can all be ‘rebuilt’,` said Mr. Nguyen An, a mobile phone seller.

According to Mr. Quoc Thang, iPhone 4 appeared in June 2010 and those who buy `built` devices, if lucky, can still own good models.

Not only iPhone 4, several refurbished iPhone 4S versions have also appeared in Vietnam.

Mr. Quoc Thang believes that, at this time, if buying an iPhone 4, users should choose the 8 GB version.
